Is the Fuel depot 3D model free for commercial use?

Yes. It is free under the 1DesignTool 3D library license: use it in personal and commercial work — games, apps, websites, renders, ads and client projects — and modify it as you like, with no credit required. What you can't do is re-sell or re-distribute the file on its own or inside a model pack.

What file format is it, and how big is it?

A single binary glTF 2.0 file (.glb), 288 KB: 2,036 triangles, 6,108 vertices and 92 materials, modelled in metres at 7.5 m × 3.7 m × 6.2 m.

Can I animate Fuel depot?

It ships as a static mesh. Its 11 named parts are separate nodes, so you can move or animate each one in your engine.

Which engines and tools can open it?

Anything that reads glTF 2.0. three.js, React Three Fiber, Babylon.js, Godot 4 and Blender import the GLB directly; Unity and Unreal Engine load it through their glTF importers. The snippets above show the exact code for three.js, React Three Fiber, Godot and Blender.

How was the Fuel depot 3D model made?

Claude Code (Claude Opus 5.5) generated it inside 1DesignTool's 3D template from a written brief, then the design kit's checks verified the geometry and the GLB before it was published. You can make your own the same way with 1DesignTool.

Fuel depot

A low-poly grass-strip avgas depot: a white storage tank with an orange band on timber cradles inside a concrete bund, with a ladder, railed walkway and vent, piped over the bund wall to a column fuel pump on a kerbed island with bollards and a fire point.

How it was made

The brief given to 1DesignTool's “3D object” template:

Fuel depot for the Airfield kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. This is one part of the Airfield kit (Low-poly style, flat-lowpoly direction): Small planes on a grass strip. Use ONLY the kit palette, by name: grass green #3a883a, hangar white #f4f1ec, signal orange #ff851a, sky blue #2e67b8, grass green dark #235223, hangar white dark #d7cebc, grass green light #5db15d, hangar white light #f9f8f6, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `era` (0–1, default 0.5) for the kit's "Era" setting wherever it makes sense on this part, and keep that id.

Note: Size: about 7.5 m wide × 6.2 m deep × 3.74 m tall (to the vent cap). The tank is 4.5 m long and 1.9 m across (about 12,000 litres), with its underside 0.55 m above the bund floor. The bund wall stands 0.25–0.70 m high. The origin is at the bottom centre of the footprint on y = 0, and the pump island faces +Z. The GLB has 2,036 triangles in 92 meshes, is static, and carries no animation clip. Normals are baked flat (non-indexed geometry). Every material is named exactly after a kit palette colour; 7 of the 12 are used. The exporter writes one material per mesh, so a colour name appears on several materials: recolour by name. era (the kit's 'Era') follows the Airfield hangar's split. Below 0.6 (the default 0.5) you get timber cradles and a tall pre-war column pump with a sight glass and lamp globe. From 0.6 up you get concrete saddles and a boxy dispenser with a hose reel. Across the whole range era also raises the bund wall. tankLength stretches the tank, walkway and bund. tankCount 2 adds a second tank behind the first (its ids are suffixed _2) and deepens the bund. The GLB is baked at default params. The params only change geometry when the scene is rebuilt in the viewer. Era 1, two 6 m tanks was also built and rendered; it was valid apart from part-id renaming, which is now fixed. glb-lint: 0 errors, 6 warnings, all expected: per-mesh material count, duplicate-named materials, non-indexed primitives, nested straps and band on the tank shell, fittings resting on parts in other groups, and the 3.74 m height versus the 1 m reference. plan-check still rejects the hyphens in the slug-based part ids this library requires (the same plan with the slug de-hyphenated passes). three-check, run with the real hyphenated ids, passes all 24 checks. The fix round made the tank part ids stable across tankCount and changed the stile steps from wood to concrete.
